Black Pin Feather Casing
Hi! I work as a trainer with rescue birds and I came across something I’ve never encountered. We have an 11 year old hyacinth, Mr. B who is molting. I was giving his a nail trim when I noticed something long and black in his feathers on the outside primaries. I looked closer and it was a pin feather casing. There were a couple through this wing. The other casings around it where or darker in hue, I’ve been helping him preen and none of his others casing look anything like it. He does have some intense stress bars, enough to where they are breaking off at the bar when he preens. He’s also a darker hued macaw, and I’ve never gone in to closely examine a molting wing, so I don’t know if that’s normal. We put a call in to ask our vet, but can’t get answer. We’re all so puzzled by it.
